'Static flow of water' illusion

(2:04) Creating the illusion of a static flow of water using sound. Explanation from a comment on YT: "In reality the sound (inaudible) being produced by the speaker causes the water stream to be periodically stopped. To the naked eye it would looks like a continuous stream of water drops. If you shoot the stream of water drops with a camera that has it's frame rate synced with the water drops the drops will appear to stay still as each frame shows the water in the exact same formation it was in in the previous frame. It's same effect that makes helicopter blades and car wheels look weird on film."

Not sure I get this. You could produce the image of "still" drops of water with a strobe light - but what does this have to do with sound?

Find out the shutter speed or fps of the camera, set the frequency of the noise to match, this would control the drop rate almost perfectly. Same as the strobe effect but using the camera's own limitations.

Yawn. I have never been so bored. I thought that maybe, just maybe, it was called bore me as it is a place on the web where one can come to alleviate boredom. Now, instead, it seems, that it is a place on the web for increasing the totality of one's boredom. Thus, I am disappointed to say the least. Raise your standards bore me! Why, oh why, must you consistently continue to post such novel rubbish?
